The Theater playbills consists primarily of theater programs and other printed ephemera from twentieth century New York City, Los Angeles, Chicago, and London. Also included are late nineteenth and early twentieth century theater programs from the Midwestern United States, scrapbooks of playbills and annotated prompt books from the same time period, and souvenir programs. A few miscellaneous publications (mostly related to the theater) are also present in this collection. It appears as though the collection was created through the combination of a number of smaller collections with differing provenances, including ones put together by Constance McCormick, Milton Lewis, and William J. Williams.
